Key Insights

1. Only Company A shows a consistent decrease in emissions year over year, dropping every year from 65.0 to 59.8 million metric tons.
2. Company C's emissions are much higher than those of the other two companies, consistently just above or below 125 million metric tons, roughly double A or B.
3. In Year 3, total emissions from all companies sum to approximately 264 million metric tons \((61.8 + 74.0 + 128.0)\).
4. Company B is unique in that it increases its emissions from Year 1 to Year 2, reaching a peak before declining again.

Step-by-Step Solution

Question 1: Identifying Consistent Emission Decreases

Complete Statement:

The greenhouse-gas emissions for Company [BLANK] decreased from the previous year for each of the three years after Y1.

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: decreased from the previous year
    • Meaning: Each year's emissions amount must be less than the previous year's value.
    • Relation to Chart: Check the emissions column for each company and compare numbers year by year after Y1.
    • Important Implications: If any year shows an increase or no decrease, that company does not qualify.
• Statement Breakdown 2:
  • Key Phrase: each of the three years after Y1
    • Meaning: We consider three transitions: Y1 to Y2, Y2 to Y3, and Y3 to Y4.
    • Relation to Chart: For each company, look at their emissions for Y2, Y3, Y4 and confirm that all are less than the previous year's value.
    • Important Implications: The requirement is strict; a single increase in any year eliminates the company.
• What is needed: Determine which company shows a consistent decrease in emissions every year after Y1.

Solution:

• Condensed Solution Implementation:
  For each company, inspect the emissions values from Y1-Y4 and check for consistent year-to-year decreases after Y1.
• Necessary Data points:
  Company A: \(65.0 \rightarrow 64.9 \rightarrow 61.8 \rightarrow 59.8\); Company B: \(69.0 \rightarrow 76.0 \rightarrow 74.0 \rightarrow 72.0\); Company C: \(123.3 \rightarrow 125.7 \rightarrow 128.0 \rightarrow 125.0\)
  • Calculations Estimations:
    Company A: \(65.0 \gt 64.9\) (decrease), \(64.9 \gt 61.8\) (decrease), \(61.8 \gt 59.8\) (decrease); Company B: \(69.0 \lt 76.0\) (increase; fails); Company C: \(123.3 \lt 125.7\) (increase; fails)
  • Comparison to Answer Choices:
    Only Company A meets the criteria, as both B and C have increases after Y1.

FINAL ANSWER Blank 1: A

Question 2: Calculating Total Y3 Emissions

Complete Statement:

To the nearest million metric tons, the total of the greenhouse-gas emissions for Companies A, B, and C during Y3 was [BLANK] million metric tons.

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: total of the greenhouse-gas emissions for Companies A, B, and C during Y3
    • Meaning: Add together the Y3 numbers for all three companies.
    • Relation to Chart: Locate the Y3 emissions for each company in the provided data and sum them.
• Statement Breakdown 2:
  • Key Phrase: to the nearest million metric tons
    • Meaning: After calculating the sum, round to the nearest whole number.
    • Relation to Chart: Sum calculated from chart must then be rounded as asked by the question.
• What is needed: Find the sum of all three companies' Y3 emissions, rounded to the nearest million metric ton.

Solution:

• Condensed Solution Implementation:
  Find Y3 values for each company, add, and round the result.
• Necessary Data points:
  Company A: 61.8; Company B: 74.0; Company C: 128.0
  • Calculations Estimations:
    \(61.8 + 74.0 = 135.8\); \(135.8 + 128.0 = 263.8\); 263.8 rounded to nearest million = 264
  • Comparison to Answer Choices:
    264 matches the correct rounded answer.

FINAL ANSWER Blank 2: 264

Summary

For blank 1, Company A is the only company that shows a decrease in emissions every year after Y1. For blank 2, the sums of the three companies' Y3 emissions total 263.8, which, when rounded, yields 264 million metric tons.

Question Independence Analysis

The questions are independent. The first requires identifying a trend in emissions for a single company; the second requires summing values across all companies. Solving one does not impact or rely on the other.
